In the high-stakes world of B2B transactions and regulated industries, a simple electronic signature often falls short of the legal and security requirements.
What your organization truly needs is a digital signature, a cryptographic seal that guarantees authenticity, integrity, and non-repudiation. The foundation of this powerful tool is the Digital Signature Certificate (DSC).
For C-suite executives, legal counsel, and IT directors, the process of how to acquire a digital certificate and generate a digital signature can seem like navigating a complex maze of Public Key Infrastructure (PKI) and regulatory acronyms.
This guide cuts through the complexity. We will provide a clear, executive-level blueprint for securing a DSC and leveraging it to create legally binding digital signatures that accelerate your business while ensuring ironclad compliance with global standards like the U.S.
ESIGN Act and the EU's eIDAS Regulation.
Key Takeaways for the Executive Reader
- ✅ Digital Certificate is Your Digital ID: The Digital Signature Certificate (DSC) is the cryptographic key, issued by a trusted Certificate Authority (CA), that verifies the signer's identity and is the prerequisite for generating a true digital signature.
- 🔒 Digital Signatures Offer Superior Security: Unlike basic electronic signatures, digital signatures use PKI to create a tamper-evident seal, providing the highest level of non-repudiation and legal defensibility for high-value contracts.
- ⏱️ The Process is Streamlined with SaaS/API: While the underlying technology (PKI) is complex, modern platforms like eSignly abstract this complexity, allowing businesses to get a digital certificate to create a digital signature and integrate signing workflows in minutes, not months.
- ⚖️ Compliance is Non-Negotiable: A DSC-backed digital signature is essential for meeting stringent regulatory requirements, including HIPAA, 21 CFR Part 11, and the Qualified Electronic Signature (QES) standards under eIDAS.
The Foundation: Understanding the Digital Signature Certificate (DSC) 🔑
Key Takeaway: A DSC is your digital passport, issued by a Certificate Authority (CA) to establish trust.
It contains your Public Key and verified identity, making it the essential first step in generating a legally valid digital signature.
Before you can generate a digital signature, you must first acquire the DSC. Think of the DSC as your digital identity card, issued and verified by a trusted third party, known as a Certificate Authority (CA) or Trust Service Provider (TSP).
This certificate is the core component of Public Key Infrastructure (PKI), the global standard for secure digital communication.
A DSC contains critical information, including the holder's name, the issuing CA, the expiration date, and, most importantly, the holder's Public Key.
This key is mathematically linked to a Private Key, which is kept secret and used only by the signer to create the digital signature.
DSC Classes: Matching Assurance to Risk
Not all certificates are created equal. CAs issue DSCs in different classes, which correspond to the level of identity verification performed and the assurance level required for the transaction:
- Class 1/Basic Assurance: Verifies only the email address and name. Suitable for low-risk transactions.
- Class 2/Moderate Assurance: Verifies identity against a pre-verified database. Often used for tax filing and corporate compliance.
- Class 3/High Assurance: Requires in-person or video verification of the individual. Mandated for high-value transactions, e-tendering, and court filings.
Understanding the difference between a basic electronic signature and a digital signature, which requires this certificate, is vital for risk mitigation.

The Step-by-Step Process to Acquire Your Digital Certificate 📝
Key Takeaway: The acquisition process is a structured, multi-step verification journey that culminates in the secure storage of your private key, often on a hardware token, ensuring non-repudiation.
Acquiring a DSC is a formal process designed to ensure the highest level of identity assurance. While eSignly simplifies the application of the signature, the certificate acquisition itself must follow strict protocols set by the CA.
The 5-Step DSC Acquisition Framework
- Select a Licensed CA or TSP: Choose a provider accredited by relevant government bodies (e.g., in the US, a CA that adheres to WebTrust standards; in the EU, a Qualified TSP under eIDAS).
- Determine the Required Certificate Class: Based on your business needs (e.g., Class 3 for high-value contracts or e-tendering), select the appropriate assurance level.
- Complete the Application and Documentation: Fill out the application form and submit verified identity and address proofs. For organizational certificates, business registration documents are also required.
- Identity Verification (KYC): This is the most critical step. Depending on the class, this may involve a video interview, biometric scan, or in-person verification to comply with Know Your Customer (KYC) guidelines.
- Certificate Issuance and Secure Storage: Once verified, the CA issues the DSC, which is typically stored on a secure hardware device, such as a USB token. This token protects the private key from unauthorized access.
This framework is the blueprint for how businesses get a digital certificate to create a digital signature.
The rigor of this process is precisely what gives the resulting digital signature its legal weight and security.
Generating the Digital Signature: From Certificate to Contract ✍️
Key Takeaway: Generating the signature is a cryptographic function: the signing software (like eSignly) uses the private key from your DSC to create a unique hash of the document, which acts as a tamper-evident seal.
The DSC is the key, but the digital signature is the lock. The actual generation of the signature is a three-part cryptographic process that happens in milliseconds within your signing platform:
- Document Hashing: The signing software runs the document through a Hashing Algorithm (e.g., SHA-256). This creates a unique, fixed-length string of characters-the document's 'digital fingerprint.'
- Encryption with the Private Key: The signer's private key (stored securely on the DSC token) is used to encrypt this digital fingerprint. This encrypted hash is the digital signature.
- Attachment and Timestamping: The digital signature, the signer's public key certificate, and a secure timestamp are all bundled and attached to the document.
Any subsequent change to the document will alter the document's hash, immediately invalidating the signature and alerting all parties to the tampering.
This is the fundamental difference between a digital signature and a simple electronic signature. For a detailed comparison, read our guide on the Difference Between E Signatures And Digital Signatures.
Quantifiable Impact: Error Reduction
The automation and integrity checks inherent in this process dramatically reduce human error. According to eSignly research, companies that fully automate their document signing process using digital signatures see an average reduction of 45% in document processing errors.
Compliance, Trust, and ROI: The C-Suite Imperative 📈
Key Takeaway: Digital signatures are not just a technology; they are a compliance tool. They provide the legal certainty required by global frameworks, translating directly into reduced risk and significant ROI.
For executives, the decision to invest in digital signature technology is driven by two factors: risk mitigation and operational efficiency.
Global Legal Frameworks for Digital Signatures
A DSC-backed digital signature is the gold standard for legal validity across the globe:
- USA (ESIGN Act & UETA): These federal and state laws grant electronic signatures, including digital signatures, the same legal weight as ink-on-paper, provided they meet requirements for intent, consent, and record retention.
- EMEA (eIDAS Regulation): The EU's regulation establishes a tiered system: Simple, Advanced, and Qualified Electronic Signatures (QES). A QES, which requires a qualified certificate and a secure creation device, holds the equivalent legal effect of a handwritten signature across all EU member states.
- Industry-Specific Compliance: For sectors like healthcare and finance, digital signatures are mandatory for compliance with regulations like HIPAA (US healthcare), 21 CFR Part 11 (FDA), and PCI DSS (payment card industry).
The robust security and audit trail provided by PKI-based digital signatures are the only way to consistently meet these stringent requirements.
ROI Benchmarks: The Business Case for Digital Signatures
The return on investment (ROI) from digital signature adoption is significant, moving beyond simple paper savings to impact revenue velocity and operational costs.
Industry benchmarks from sources like Gartner indicate that paper-based processes can cost up to $40 per document in materials, labor, and storage.

Frequently Asked Questions
What is the difference between a Digital Signature Certificate (DSC) and a Digital Signature?
The DSC is the credential; the Digital Signature is the action. The DSC is an electronic file issued by a Certificate Authority (CA) that verifies the signer's identity and contains their Public Key.
The Digital Signature is the cryptographic result of using the Private Key (associated with the DSC) to encrypt a document's hash, creating a tamper-evident seal on the document.
Is a digital signature legally required for all documents?
No, a digital signature is not legally required for all documents. Simple electronic signatures (SES) are sufficient for many low-risk commercial transactions under the U.S.
ESIGN Act and UETA. However, digital signatures are often mandated or highly recommended for:
- High-value financial transactions.
- Government e-tendering and e-procurement.
- Documents requiring strict regulatory compliance (e.g., 21 CFR Part 11 in Pharma, QES under EU eIDAS).
- Any transaction where non-repudiation is critical.
How long does it take to acquire a Digital Signature Certificate?
The time required varies significantly based on the certificate class and the identity verification process. Basic certificates (Class 1/2) can be issued in a few hours to a day.
High-assurance certificates (Class 3/QES), which require rigorous in-person or video-based Know Your Customer (KYC) verification, can take several days. Modern platforms like eSignly simplify the use of the certificate, but the verification process is strictly controlled by the Certificate Authority to maintain legal integrity.
